Integer Review (Chapter 2 Lessons 1 and 2) Review: Sets of numbers you’ve already studied: Natural numbers (also called the counting numbers) {1, 2, 3, 4, …} II. Whole numbers {0, 1, 2, 3, 4, …}

Lesson concept: A.Integer – a positive or negative whole number. (p.56) Integers = {…,-3, -2, -1, 0, 1, 2, 3, …}  No fractions or decimals  Zero is neither positive or negative

What do you think the answer is to the following problem?

When adding integers, there are two cases to consider: Adding integers with the same sign. Ex 1, = ________ –3 + (–12) = _______ a) Add the values together b) Carry the sign of the numbers into the answer

Adding integers with different signs. Ex 2, 10 + (–4)= ______ 8 + (–12) = ______ a) Subtract the two numbers b) Use the sign of the number with the greater absolute value. Give it a try! 13 + (–16) = ____ 24 + (–4) = ____

Defn. Opposites – two numbers with the same absolute value but different signs. (p. 66) Ex 3, 5 and –5 Defn. Additive inverse – the opposite of a given number (p. 66) Ex 4, The additive inverse of 3 is ___ What is the additive inverse of –8? _____
